Strong decays of the states
Through the spin rearrangement scheme in the heavy quark limit, we have
performed a comprehensive investigation of the decay pattern and production
mechanism of the hidden beauty di-meson states, which are either composed of a
P-wave bottom meson and an S-wave bottom meson or two S-wave bottom mesons. We
further extend the corresponding formula to discuss the decay behavior of some
charmonium-like states by combining the experimental information with our
numerical results. The typical ratios presented in this work can be measured by
future experiments like BESIII, Belle, LHCb and the forthcoming BelleII, which
shall provide important clues to the inner structures of the exotic states.Comment: 21pages, 12table
